While aware of other reviews similar to this, I must say that I'm very disappointed by this not being the original version of Z; the controls are awful, the interface is just different than the original, which makes it lose the great appeal it had the twenty something years ago when I tried it for the first time. It's clunky, slow, and not really as great as it once was. If it's someday changed to the original, I'll gladly change this review.
